NTFS Warning ID 50, ID 140 User profile disk

Hi all,

I've a deployment of RDS 2012 with user profile disk enabled. The server hosting the share for user profile disk is a Windows Server 2012 (so it speaks SMB 3).

When user log off from his session I see the following warning on the session host:

NTFS ID 50
